English Summary

The U.S.-South Korea alliance, anchored in the Korean War (1950-1953) and formalized through the 1953 Mutual Defense Treaty, remains a cornerstone of regional security with over 28,500 U.S. troops permanently stationed in the ROK. Facing escalating threats from China, Russia, and North Korea, both nations are prepared to expand South Korea's operational role and broaden the alliance's strategic mission beyond traditional deterrence. Congress holds key levers to modernize the partnership through strategic flexibility, wartime operational control realignment, burden-sharing arrangements, extended deterrence guarantees, and defense industrial cooperation—signaling recognition that evolving Indo-Pacific threats demand enhanced coordinated military and strategic capabilities.

中文摘要

美韓同盟的基礎源於韓戰(1950-1953),並透過1953年《共同防禦條約》正式確立,至今仍是區域安全的核心支柱,美軍超過28,500名人員常駐韓國。面對來自中國、俄羅斯和朝鮮半島的威脅日益升級,兩國正準備擴大韓國的戰略作戰角色,並將同盟的戰略使命拓展至傳統威懾範疇之外。國會掌握著關鍵的推動槓桿,可透過戰略彈性、戰時作戰指揮重組、分擔責任機制、延伸威懾保證以及國防工業合作等方式,來現代化這段夥伴關係,這表明雙方已認知到不斷演變的印太威脅,要求提升協調的軍事和戰略能力。

    The article argues that the Federal Reserve's recent rate hike decision, while justifiable on inflation grounds, highlights a critical lack of an underlying, transparent policy framework. The core problem is that the Fed's decisions appear discretionary, leading to market uncertainty because the committee's judgment, rather than clear data, dictates policy shifts. The author proposes that the Fed adopt a formal monetary policy rule—an algebraic formula linking the target rate to indicators like inflation and unemployment—to replace subjective guidance. Implementing such a rule would provide market predictability, enhance transparency, and shield the Fed from political attacks by making deviations from the standard easily quantifiable.

    The ongoing Ebola outbreak in the DRC serves as a critical warning that the global health security system is fundamentally unprepared for future biological threats. The difficulty in containing this outbreak is compounded by the rising risk of emerging pathogens and the growing potential for AI misuse in bioweapon development. Policy must therefore shift from reactive, crisis-driven funding to sustained, proactive investment in resilient public health infrastructure, particularly in conflict zones. Addressing this requires strengthening global surveillance, ensuring consistent international cooperation, and mitigating the intersection of conflict, climate change, and disease spread.

    Despite MOUD being the standard of care for opioid use disorder, access remains severely limited in Community Mental Health Centers (CMHCs), which serve the primary population with co-occurring disorders. A Design Lab pilot identified payment limitations and regulatory complexity as the chief barriers to implementation. The most feasible and high-impact strategy identified was establishing a structured learning exchange between CMHC leaders and insurers to improve reimbursement understanding. Policymakers and payers are therefore advised to pilot this learning exchange model to initiate broader payment reform and expand evidence-based care for this vulnerable population.

    The article argues that modern conflicts are increasingly defined by attrition, driven by three strategic gaps: the difference between nominal military power and usable capacity; the difficulty of achieving breakthroughs in a technologically advanced battlefield; and the detachment of military means from clear political objectives. Evidence from Ukraine and the Middle East demonstrates that sustained logistics, rapid technological adaptation, and proxy networks are now more decisive than sheer military size. For policymakers, this implies a strategic shift away from seeking short, decisive victories toward preparing for prolonged, high-cost engagements, requiring a focus on sustainable supply chains and defining concrete, attainable political end-states.

    Congress has significantly expanded presidential tariff authority by passing the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, allowing the executive to impose up to 100% tariffs on key buyers of Russian energy and sanctions enablers. The article argues that this legislation represents a dangerous abdication of Congress's Article I authority, as it grants the executive vast, discretionary power without specifying criteria for enforcement. Historically, the executive could claim tariffs were its own doing; however, by writing and passing this new authority, Congress now owns the resulting trade policy and its economic consequences. This shift implies that future tariffs will be viewed by the public as a direct legislative action, potentially undermining the administration's credibility and creating political vulnerability.
